Title:
MARINE DEGRADABLE POLYHYDROXYALKANOATE COMPOSITION, MOLDED BODY AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/245997
Kind Code:
A1
Abstract:
A marine degradable polyhydroxyalkanoate composition, a molded body and a preparation method therefor. The polyhydroxyalkanoate composition comprises: 38-89.5 parts of a polyhydroxyalkanoate, 10-30 parts of other completely biodegradable resin, an additive and 0-30 parts of a filler. The additive comprises: 0.1-0.5 parts of a chain extender, 0.1-1 part of an antioxidant and 0.1-1 part of a lubricant. The molded body prepared on the basis of the polyhydroxyalkanoate composition has high marine degradability, and the provided preparation method can improve the processability and processing efficiency of the blended composition.
